Unlike cheapie online polls I regard the four phone surveys that we get each month as an event. The one out today is from Ipsos-MORI and shows Labour up to their highest level with the firm since the 2001-2005 parliament.

This pollster, it should be recalled, uses only those 100% certain to vote in its headline figures.

The firm also has its leadership ratings which have been asked in the same way since before Maggie Thatcher’s victory in 1979.

The latest breakdown are above and show all three party leaders moving forward.
